If you're a snowmobile rider, when winter rolls around, you should always perform some basic maintenance to get ready for the season. One of the most important things to do is change your chain case oil. This is important for two reasons:
- Chain case oil breaks down with heating and cooling cycles
- Chain case oil can get contaminated by both water and metal slivers from the chain and sprockets
Simply put, a clean and well-lubed chain means a well-performing sled!
How to change your chain case oil:
1. To start, place a drain pan/bucket under the chain case drain plug and remove the plug to drain the oil.
2. Next, remove the chain case cover to expose the gears, chain, and inside of the chain case.
